Air assist nozzle for the Sainsmart Genmitsu LE5040 laser engraver. This part replaces the stock acrylic spacer that the laser module attaches to. Air hose hole is sized as a friction fit for standard vinyl aquarium air line. There are 2 versions: one for the standard lens as supplied, and the "hi-res" version works with the JTech Photonics hi-res lens, which has a shorter focus distance.
